Classic Mini DIY: Remote Gearbox Assembly/Rebuild Pt 2

Beginning in 1968, all 4-synchro boxes had a split needle roller bearing under 1st gear.

Large bearing that carries the first motion shaft in the gear case starting in 1968-on.

Two of these are needed in 4 synchro laygears before 1979, and only one for later A+ gears. Fits first motion end of laygear. Sold each.

Small caged needle roller bearing fits both ends of laygear on 3-synchros and 1st gear end of 4 synchros to 1979. Sold each.

Double-row ball bearing supports the mainshaft in the center web of the gearbox. We stock the correct bearing with full-width outer race for best reliability. Manufactured in Germany by RHP.

Improved pipe that moves the oil pick-up point towards the center of the engine

Circlip, or stop ring, around the AAU1365 double ball bearing on the mainshaft.

Detent Ball. 3 & 4 Synchro Gearbox.

Detent Spring inside of synchro hubs in 4-synchro gearbox. Use six (6) per gearbox. Sold each.

Gear, First/Reverse. 4 Synchro Gearbox. New, aftermarket.

Third gear, 4 synchro transmission. 21 teeth. Pre-A+ only.

Stronger material and precision machining are featured in this improved layshaft; made from a special grade of steel (EN36) and heat-treated to minimize wear.

The 14mm nose of the mainshaft is its weak point, and can be badly worn or pitted. Always replace the mainshaft if this wear is present,

Second Gear. 4 Synchro Gearbox and early rod change. Aftermarket.

First/second gear synchonizer hub assembly for all 4-synchro tranmissions. Replaces 22G2263. See also DAM7455-RING for outermost slider ring only.

Laygear thrust washer on 4th gear end which is one size only. The first gear end is the adjustable laygear washer end but these are obsolete on Pre A-plus layshafts. This one fits all 4-synchro gearboxes.
